Boligsiden Scraper

Extract property listings and historical sold prices from Boligsiden.dk, Denmark's #2 real estate portal. This actor pulls prices, sizes, rooms, energy labels, monthly costs, images, and realtor details for houses, apartments, and holiday homes across Danish municipalities — plus Boligsiden's registered sold-price history (solgte), not just current asking prices.

Why use this actor?

Boligsiden aggregates listings from essentially every Danish realtor and publishes the country's official land-registry sold-price history (Tinglysningen) alongside current listings. That combination — live asking prices plus verified historical sale amounts down to street level — makes it useful for price-trend analysis, comparable-sale research, and market-entry due diligence in a way a for-sale-only feed can't match.

Use cases include market analysis by kommune, price-per-square-meter benchmarking, relocation and mortgage-appraisal research, academic housing studies, and competitor tracking for proptech and real estate agency tools.

How to scrape Boligsiden data

1. Go to the actor's page on the Apify Store
2. Choose a kommune (Copenhagen, Aarhus, Odense, Aalborg, Esbjerg, Kolding, or all of Denmark) or paste a Boligsiden.dk search URL
3. Pick search type: for-sale listings (tilsalg) or sold prices (solgte)
4. Click "Start" to run the scraper
5. Download results as JSON, CSV, or Excel when complete

The actor fetches pages through Bright Data's Web Unlocker to get past Boligsiden.dk's Cloudflare managed challenge, then extracts data from the site's own server-rendered React payload for maximum reliability — no fragile CSS scraping for the fields that matter most.

Cost estimate

This actor fetches every page through Bright Data's Web Unlocker (one request per search page, not a full browser session). Approximate costs:

• ~50 for-sale results (1 search page): $0.01-0.03 in platform credits
• ~500 for-sale results (10 search pages): $0.10-0.30 in platform credits
• ~20 sold-price results (1 search page): $0.01-0.03 in platform credits (sold pages return fewer results per request, so cost per result is proportionally higher)

Actual usage cost only settles once the run reports SUCCEEDED — reading the dataset from a still-running run will undercount what you'll actually be charged.

Tips for best results

• Start small — test with maxResults: 20 before running large scrapes.
• Sold-price search always needs a specific kommune. Boligsiden.dk has no working nationwide sold-price listing page — only /kommune/{slug}/solgte returns real data. If you set searchType: sold with kommune: denmark, the actor logs a warning and falls back to Copenhagen automatically.
• customKommuneSlug unlocks any of Denmark's 98 kommuner — the curated kommune list covers the six largest markets; for anywhere else, browse boligsiden.dk/kommune/{slug}/tilsalg and copy the slug from the URL.
• For-sale listings carry far more fields than sold listings — rooms, energy label, build year, images, and realtor are only present on the current-listing record, not on historical sale registrations.

Limitations

• Boligsiden.dk fronts every page with a genuine Cloudflare managed challenge. This actor routes requests through Bright Data's Web Unlocker to get past it.
• Free-text (?q=) and zip-code (?zipCodes=) query parameters don't filter results server-side on this site — only the /kommune/{slug}/... URL path reliably scopes a search, so this actor uses that path pattern rather than query-string filters.
• rooms, landSurface, buildYear, epcScore, imageUrl(s), and agencyName are always null/absent on sold listings. These live on the original for-sale listing record, not on the land-registry sale registration Boligsiden shows for historical sales — this is a real data-model difference on the site, not a scraping gap.
• Sold prices reflect the most recent verified land-registry sale registration for an address. Some addresses carry additional non-arm's-length registration records (e.g. family transfers, foreclosures) alongside ordinary sales — the actor prefers the most recent ordinary-sale registration and skips registration types the site itself flags as non-standard, to avoid reporting a non-market placeholder amount as the sale price.
• Price data on for-sale listings reflects Boligsiden's own asking price, not a guaranteed final sale price.
• The actor scrapes the public website. No login or authentication is used.
